The film emphasizes that catalysts are typical chemical reactants, being unique
only in that catalysts are regenerated during the reaction. It demonstrates and interprets three simple catalyzed reactions: the decomposition of formic acid, using sulfuric acid as catalyst; the reaction between hydrogen and oxygen, using pure platinum as catalyst; and the reaction between acidified benzidine and hydrogen peroxide using peroxidase in human blood as catalyst. Animation shows what takes place on the molecular level in a catalyzed reaction. Potential energy curves show the relationship between uncatalyzed and catalyzed reactions.
